Embodiment 1

[0020] This embodiment provides a skeleton oil seal torque testing device, which is specifically as follows:

[0021] The skeleton oil seal torque testing device includes a support base 1, a prime mover 2, a transmission shaft A3, a ZJ type torque speed sensor 4, a transmission shaft B5, a skeleton oil seal 6, a skeleton box 7, a gear oil 8 and an advanced computer 9, and is characterized in that : The prime mover 2 is installed on the rightmost part of the support base 1, the ZJ type torque speed sensor 4 is connected with the prime mover 2 through the transmission shaft A3, and the skeleton box 7 is connected with the ZJ type torque sensor through the transmission shaft B5 The rotation speed sensor 4 is connected, the gear oil 8 is placed inside the skeleton box 7, the skeleton oil seal 6 is placed at the position where the skeleton box 7 connects with the transmission shaft B5, and the high-level computer 9 and the ZJ type torque speed The sensor 4 is connected and is locat...

Embodiment 2

[0024] see Figure 1-2 , the present embodiment provides a detection method for a skeleton oil seal torque testing device, comprising the following steps:

[0025] First, the prime mover 2 drives the transmission shaft A3 to rotate, so that the ZJ-type torque speed sensor 4 can dynamically collect the rotation speed, friction torque, and power loss generated by the skeleton oil seal 6 relative to the transmission shaft B5, and connect it to the ZJ-type The advanced computer 9 on the torque speed sensor 4 performs dynamic collection, forms corresponding numerical values ​​and dynamic curves, and finally generates corresponding reports.

[0026] Under the premise of not making major changes to the standard skeleton oil seal test bench, the present invention has good results through actual transformation and application testing, which not only meets the customer's demand for this data, but also provides design and development personnel with information in the process of product d...

Abstract

The invention provides a framework oil seal torque testing device and a detection method thereof; the device comprises a support pedestal, a prime mover, a transmission shaft A, a ZJ type torque rotating speed sensor, a transmission shaft B, a framework oil seal, a framework box body, a gear oil and a high-grade computer; the prime mover is arranged on the right-most portion of the support pedestal; the ZJ type torque rotating speed sensor is connected with the prime mover via the transmission shaft A; the framework box body is connected with the ZJ type torque rotating speed sensor via the transmission shaft B; the gear oil is arranged in the framework box body; the framework oil seal is arranged in a joint slot position between the framework box body and the transmission shaft B; the high-grade computer is connected with the ZJ type torque rotating speed sensor. The testing device and the detection method have been applied to the transmission test industry for many years; the matureand reliable torque rotating speed sensor and the computer can gather related data, thus dynamically and statically measuring the startup torque and the friction torque under different rotating speeds.

Description

technical field [0001] The invention relates to the technical field of starting torque and friction torque testing of skeleton oil seals, in particular to a skeleton oil seal torque testing device and a detection method thereof. Background technique [0002] The existing skeleton oil seal testing machine can only measure whether the oil seal leaks oil under different rotational speeds, different temperatures, and different eccentricities within a specified time, and cannot dynamically measure the starting torque and friction torque of the oil seal. There is no corresponding in the oil seal industry. measurement standard. The starting torque of the skeleton oil seal and the friction torque generated by the shaft at different speeds have always been difficult to measure, and there is no corresponding measurement method. The loss of the skeleton oil seal to the entire transmission system of the vehicle is usually negligible in the early stage, but the skeleton oil seal is well ...
